HD cable STB processor with integrated demodulator and low power standby controller

The STiH223 uses the latest process technology to provide a cost-effective, feature rich, highly integrated SoC for set-top boxes (STBs). It is targeted at the advanced decoding STB market across American and Asian cable networks that utilize the ITU-T J.83 annex B physical layer. It is suitable both for operator (with advanced security) and retail markets.

The STiH223 provides a solution for operators and manufacturers to specify a range of cost-effective, high performance STBs, including basic zappers, interactive STBs, and DVR STBs with content delivery possible using broadcast or broadband networks or both (hybrid STBs).

The STiH223 integrates a high performance cable receiver, supporting reception, channel demodulation, and forward error correction (FEC) and is fully compliant with the ITU-T J.83 annex B standard.
